Tein Mono Racing Coilovers Mazda MX-5 Miata NDERC NDERE 16+

TEIN Mono Racing Coilovers for Mazda MX-5 Miata NDERC NDERE (2016 on) – Track-Focused Mono-Tube, Camber Adjustable Mounts

TEIN Mono Racing is a motorsport-derived coilover kit for the Mazda MX-5 Miata NDERC NDERE, giving you adjustable ride height and damping to set the car up properly for track days and competition. TEIN specifies 14 kgf/mm front and 10 kgf/mm rear spring rates for this application (other rates can be chosen when ordering).

Mono Racing is TEIN's coilover for drivers who regularly do track days. It uses mono-tube dampers with TEIN's ADVANCE M.S.V. valve, full-length height adjustment and, on most strut cars, pillow-ball top mounts derived from TEIN's Super Racing kit with independent camber and caster adjustment. Springs are matched to the car, and TEIN lets you choose different spring rates when ordering.

The damper bodies get TEIN's two-layer powder coat, and the height-adjustment threads are protected by TEIN's low-friction ZTP coating, which resists rust and stone chips and helps stop the spring seats seizing. TEIN springs are cold-formed from SAE9254 spring steel and powder coated, and TEIN designs them to resist sagging over time.

Spring rates and ride heights are TEIN's application data. Heights are measured against the car's standard ride height and are a guide only: the result on your car depends on its condition, wheels and tyres, and load.

Key Features

Please check before ordering:

• 4-cylinder, 2.0-litre.

Installation

The kit replaces the complete original strut and damper assemblies. Set the ride height on the bench by screwing the damper body in or out of its lower bracket, then fine-tune on the car. TEIN pre-tightens the lower bracket lock rings only, so they must be fully tightened at fitting and checked regularly. Never shorten the body beyond TEIN's stated range. Tighten the top nut with a torque wrench while holding the piston rod on its flats; over-tightening can damage the adjuster. Leave suspension arm bolts loose until the car is back on its wheels, then torque them at normal ride height so the bushes aren't preloaded. TEIN advises lowering by no more than 30-40 mm to start with, keeping the front level with or 5-10 mm lower than the rear. Let the springs settle for a few days, recheck the height and lock rings, then have a full four-wheel alignment done. Fitting needs spring compressors (where strut assemblies are rebuilt), a torque wrench and a good understanding of the car's suspension. We recommend professional fitting.

Upgrade Further

Lowering changes the anti-roll bar geometry. TEIN's adjustable drop links let you correct it: Tein Front Adjustable Drop Links Mazda MX-5 Miata NDERC, Tein Front Adjustable Drop Links Mazda MX-5/Roadster Miata RF NDERC. Add a TEIN EDFC5 controller with motor kit EDK05-12120 to adjust damping from the driver's seat. Contact us for pricing.

Will this kit fit my Mazda MX-5 Miata NDERC NDERE?

This kit (TEIN part VSMC6-K1LS3) is listed for the models in the Fitment section above. Check your chassis code, year and trim against that list, along with any notes under it. If you're unsure, send us your registration or VIN before ordering and we'll confirm.

How low will my Mazda MX-5 Miata NDERC NDERE go?

As supplied, TEIN's data puts the car approx. 45-50 mm lower than standard at the front and approx. 40-55 mm lower than standard at the rear. TEIN recommends staying within 25 to 55 mm below standard at the front and 30 to 65 mm below standard at the rear. Wheels, tyres and the car's condition all affect the final height.

Can I adjust the damping?

Yes. The 16-level adjuster changes compression and rebound together: 0 is the stiffest setting and 16 the softest. Start from TEIN's recommended setting and change it a few clicks at a time.

Does it work with TEIN EDFC?

Yes. You'll need TEIN's EDFC5 controller kit plus motor kit EDK05-12120 for this car, both sold separately. EDFC lets you change damping from inside the car.

Are top mounts included?

Yes. Pillow-ball top mounts are included. They give sharper steering feel and camber adjustment, but can transmit a little more noise than rubber mounts.

Do I need a wheel alignment after fitting?

Yes. Changing ride height alters camber and toe, so have a full four-wheel alignment done once the springs have settled and the height is final.

Are TEIN coilovers road legal in the UK?

Coilovers can be used on UK roads as long as the car stays roadworthy: keep a sensible ride height, enough clearance and correctly aimed headlights. Modifying your suspension should be declared to your insurer.

Is Mono Racing too stiff for the road?

Mono Racing is aimed at regular track use, so it's firmer than Flex Z or Mono Sport, but the 16-level adjuster gives a usable range. If the car is mainly used on the road, Mono Sport is usually the better choice.

What warranty do TEIN coilovers come with?

TEIN UK covers its suspension for 12 months from the date of purchase against defects in materials and workmanship. Keep your invoice, as it's needed for any claim.
